Communication depends on Voyager’s 3.7-metre high-gain antenna transmitting narrow, low-power X-band radio signals. Those signals are captured by NASA’s Deep Space Network, three arrays of huge dishes in California, Spain and Australia, which amplify and decode the faint transmissions. The probe transmits slowly and in short bursts, storing data onboard and sending it in low-rate streams that the DSN reconstructs …

In June 2025, data from NASA’s Voyager 1 and Voyager 2 confirmed a dramatic finding: a region at the edge of the heliosphere with temperatures between 30,000 and 50,000 kelvin. Often described as a “wall of fire,” this boundary—known as the heliopause—marks where the Sun’s solar wind collides with the interstellar medium. The discovery provides an unprecedented look at the …

When NASA’s Voyager 1 spacecraft sailed past Jupiter in 1979, it recorded a stunning and unusual phenomenon—plasma waves as it crossed the planet’s bow shock. This haunting sound, captured 46 years ago, is a striking reminder of the vast and mysterious world that lies at the heart of our solar system. The recording, which is not quite Holst’s The Planets …

● ● • We dissent to changes to NASA’s Technical Authority capacities that are driven by anything other than safety and mission assurance. The culture of organizational silence promoted at NASA over the last six months already represents a dangerous turn away from the lessons learned following the Columbia disaster. Changes to the system of …
